错误：超出域错误mathprog

Question

我是GNU GLPK的新用户，我正面临着这种类型的错误。 你能帮忙解决一下吗？ 错误消息：

Generating EQ_SpecifiedDemand...
OSeMOSYS_test1-22.txt:193: SpecifiedAnnualDemand[TUNISIA,ELEC,2010] out of domain MathProg model processing error

以下是我的参数：

param SpecifiedAnnualDemand{y in YEAR,f in FUEL,r in REGION};

param SpecifiedDemandProfile{y in YEAR, l in TIMESLICE, f in FUEL, r in REGION};

param YearSplit{y in YEAR,l in TIMESLICE};

s.t. EQ_SpecifiedDemand{r in REGION, l in TIMESLICE, f in FUEL, y in YEAR}: 

SpecifiedAnnualDemand[r,f,y]*SpecifiedDemandProfile[r,f,l,y] / 

YearSplit[l,y]=RateOfDemand[r,l,f,y];

任何线索？
